Official engine, trustworthy results
EPANET 2.2 (US EPA) compiled to WebAssembly: the same equations, the same results as the world reference. Computation stays 100% local in your browser.
Model and simulate drinking water networks right in your browser: draw on satellite imagery, run 24 h/7 d simulations, check water quality, sectorize into DMAs. No installation, no compute server — everything runs on your machine.
The same hydraulic solver trusted worldwide for 30 years — delivered in a modern, georeferenced, affordable tool.
EPANET 2.2 (US EPA) compiled to WebAssembly: the same equations, the same results as the world reference. Computation stays 100% local in your browser.
Trace pipes and junctions on satellite imagery — Dakar or anywhere else. Geodesic lengths are computed automatically; no more manual measurements.
Pipe sizing, starter network generation, diagnostic help: an assistant that speaks the language of urban hydraulics.
Free to learn and prototype. Pro at 5,900 FCFA/month payable via Wave, or $9.99/month by card. No commitment, no €5,000 license.
Single-period or 24 h/7 d simulation: elevated tank level cycles, demand patterns, pump on/off controls.
Chlorine decay, water age and source tracing to identify which resource supplies each neighborhood.
Open models from EPANET Desktop, WaterGEMS or Porteau, and re-export a standard .INP file at any time. Your data is never locked in.
Load GeoJSON or Shapefile layers to build the model straight from your existing asset inventory.
Sizing, network generation, context-aware hydraulic answers. 3 requests/day on Free, 50/day on Pro.
Fit pipe roughness coefficients to your field pressure and flow measurements — no more manual trial and error.
Printable reports, result tables exportable to CSV, public project sharing via a simple link.
On/off rules based on tank levels or schedules: validate your pumping strategies before applying them in the field.
DMA sectorization and leak pre-location using the minimum night flow method. Details below.
Non-revenue water is fought with method: split the network into district metered areas (DMAs), track the minimum night flow, and intervene where it drifts.

Hydraulic computations run 100% in your browser (EPANET 2.2 engine in WebAssembly): your model does not need to leave your machine to be simulated. Only the projects you choose to save to the cloud are stored on our servers, and you can export or delete your data at any time.
Yes. Hydro Easy imports and exports the standard .INP format. You can open a model created in EPANET Desktop, WaterGEMS or Porteau, edit it, then re-export it — the round trip is by design, so your data is never locked in.
Once the app is loaded, simulations run locally: a dropped connection does not interrupt a running computation. Connectivity is only needed for the satellite basemap, cloud sync and the AI assistant.
From the app, pick the Pro plan then "Pay with Wave": you pay 5,900 FCFA/month straight from your Wave account, no bank card needed. Card payment ($9.99/month) remains available for users outside the FCFA zone.
Yes, at any time and without justification: the subscription has no commitment. You keep Pro access until the end of the period already paid, then your account simply reverts to the Free plan — your projects remain exportable as .INP.
Open the app, trace three pipes on your city's map and run your first simulation — in under five minutes, with nothing to install.
